<p>The <code>fluentd</code> adapter is designed to deliver Istio log entries to a
listening <a href="https://www.fluentd.org">fluentd</a> daemon.</p>

<p>This adapter supports the <a href="https://istio.io/docs/reference/config/policy-and-telemetry/templates/logentry/">logentry template</a>.</p>

<section>
<p>Configuration parameters for the fluentd adapter.</p>

<p>This adapter accepts instances of kind: logentry. It then routes
those logentries to a listening fluentd daemon with minimal
transformation. Fluentd uses a &ldquo;tag&rdquo; for all logs. The &ldquo;Name&rdquo; of
the logentry is used as the &ldquo;tag&rdquo;, unless the logentry already has
a variable &ldquo;tag&rdquo;.</p>
